Image ProcessingXiaoyingMid-career hireXiaoying joined NSK in 2019 as a mid-career hire, after previously working in production line automation at a robotic systems integration company. After joining NSK, she has worked in the Automation Group of the Intelligent Technology Development Department, developing mobile collaborative robots to automate alignment and removal of components on the production floor. She is also currently interested in 3D simulators and has been tasked with utilizing 3D virtual systems to shorten development time when developing new equipment.Comments from team managerCommentXiaoying has prior experience meeting the high demands of customers as a systems integrator. She is also a foreign national, so she brings a fresh perspective to the team. I hope that the unique qualities and skills she brings to the table will inspire our manufacturing and development team. She is very dedicated and driven, and is always focused on the end goal! I find her willingness to learn new technologies such as real digital twin1 and her positive attitude wonderful.NSK’s unique development technology that generates an accurate virtual copy of the device or product being developed. This allows engineers to arrive at solutions that break through preconceived ideas by observing the device or product from the inside in detail and understanding its true nature through deduction and modeling.

Robot ProgrammingHirokiNew graduate hireHiroki joined NSK as he was interested in working for a business-to-business (B-to-B) manufacturer that supports the foundations of society. For around three years after joining NSK, he worked in mechanical design and equipment start-up for bearing assembly and inspection equipment in the Manufacturing Engineering Center's Manufacturing Equipment Development Department. He then transferred to the Intelligent Technology Development Department's Automation Group, where he is working to develop mobile collaborative robots.Comments from team managerCommentOur work in the Automation Group requires all-round knowledge and experience in machinery, electronics, and systems, and it is not a job that can be done by a specialist in any one technology. Hiroki moved to the group after 3 years of working in mechanical design with a desire to take up a new challenge, and he has worked diligently and enthusiastically even when tackling a task for the first time. His willingness to learn new technologies is very admirable. Plus, he is a great moodmaker and team player!
Leveraging robotics and image processing
to achieve
plant automation and increased efficiency
At the center, a relatively new organization called the
Intelligent Technology Development Department was launched
only five short years ago. At NSK's Manufacturing
Engineering Center, our engineers develop and implement
production equipment with the aim of improving product
inspections and enhancing productivity through automation
and increased efficiency.
In this interview we sat down for a chat with the members of the Automation Group, which is on a mission to develop innovative automated equipment using the latest in robotics and image processing technology. Together with their team leader, Takahiro, Hiroki, and Xiaoying work together as a four-person unit to develop automated production equipment through autonomous robotic technology.

The team pooled their respective strengths to develop a robot that could align, load, and unload components
On the production floor, loading, unloading, and transporting
components is a complex task, making it difficult to automate.
As a solution to this problem, this team developed a mobile
collaborative robot that works like a human arm and can be
adapted to a variety of different production machines. By
mounting a collaborative robot on top of a commercially
available autonomous mobile robot (AMR) and adding a robotic
hand for loading and unloading the components as well as image
processing functionality, the team succeeded in creating the
perfect device for automating this complex task.
Putting our heads together to find new solutions with new technology
Tell us about how you approach your work.
Takahiro
Typical manufacturing engineering work consists of
maintaining the plant and building new production lines by
reinstalling machines for repeat products. However, we do
not simply wait for requests. Instead, I visit the plants
and work with managers to figure out what their needs are
and determine what kind of equipment would make operations
more efficient. Then I share the image and specifications
of the equipment we discussed with the younger members of
our team like Hiroki and Xiaoying. Once I have them on
board with the concept, we split up the tasks that need to
get done and dive into the development process.
What roles did you each play in this project?
Xiaoying
I was in charge of making the robot adjust its position
and identify the components it needed to pick up and
transport through image processing. To use the human body
as an analogy, I essentially helped create the eyes. Since
this was a mobile robot, I developed an imaging function
to check the position of the robot and confirm that the
required number of components were loaded onto it.
Hiroki
I was primarily in charge of creating the programming for
the robot’s movements and how it handled the components as
well as the motion of the unit overall. Essentially, I
developed and designed the brain of the robot that tells
it when, how, and how far to move.
When you hit a wall while working on this project, how did you overcome it?
Hiroki
Well, we ran into a lot of walls (laughs). We would share
the problems and challenges we were facing with the team,
and put our heads together to come up with a solution. If
we don’t maintain a regular understanding of each others’
work, we would each be left to face those challenges and
problems on our own. When all of our team members
understand what the others are working on, it's a lot
easier to give each other advice. If you’re struggling
with something, the person next to you will always have a
helpful idea.
I think we can provide that support for each other because we all have a common understanding of a single goal. Each of us is constantly thinking of how we can develop even better technology. That's why we have an environment in which people are quick to put their ideas out on the table, and everyone is ready to listen.

Xiaoying
There are a lot of people you can ask for advice if you
don’t understand something because the people in our group
have a diverse array of technical backgrounds. I’m
thankful to be on a team where everyone comes together to
find a solution whenever anyone has a problem.
When developing this robot, I ran into a lot of problems that I wasn’t expecting. Whenever an issue came up, I would consult with Hiroki and we’d tackle the problem together to come up with a solution. When the two of us couldn’t solve the problem alone, we would consult with our team leader or Takahiro, and through collaboration we would arrive at a solution.

Takahiro
Since our team leader was also there, I generally held my
tongue and let them work out the problem based on their
own ideas (laughs).
In what ways do your team members help you out?
Xiaoying
Hiroki sits next to me, so he is the first person I go to.
Neither Hiroki nor I have a lot of experience with IT
system development, so we are learning together. However,
Hiroki always helps me out because he immediately notices
the small details. He is also very open-minded and
imaginative, and suggests approaches that I would have
never thought of, which helps drive my work forward. With
this robotics project, the screen layouts he created for
the robot are extremely well designed and user-friendly.
Hiroki
Since I transferred to this division in the fall of 2020,
I am a newcomer to the team, so I didn’t really understand
what was going on at first. But whenever I would ask
Xiaoying a question, she would always give me a detailed
explanation. I am very thankful for her help, because once
I understood the current status of the project, I was
finally able to offer up my own opinions and contribute my
own strengths as an engineer.
Moreover, I requested to be transferred to this division because I wanted to try my hand at things outside the realm of machine design. Despite still being inexperienced, Takahiro and our team leader give me a wide range of tasks so long as I show that I have a firm understanding of what needs to be done. I feel that this is because we trust and support each other as a team.

Is there anything you would like to thank your team for?
Xiaoying
I am of foreign nationality, and it was my first time
changing companies, so I was a little apprehensive.
However, everyone welcomed me into the team and made me
feel right at home.
Takahiro
The culture and customs that someone is brought up with
may be different from your own, but I think that basically
you should respect an individual for who they are. Of
course, NSK has a number of its own customs that it has
cultivated over the years, but these aside, I think we
should eliminate the mindset that we have to do things a
certain way because this is Japan. So for me, I have no
intention of treating Xiaoying any differently than I
would anyone else. That being said, coming from a
different background I think that Xiaoying probably felt
some pressure when she first joined the team.
NSK may have a 100-year long history, but there are still practices that should be changed. That is why I aim to be open to the proposals that Xiaoying brings to the table, and leverage this to change NSK for the better.

Xiaoying
When I first joined the team, it took a bit to get used to
each other, but everyone was very welcoming and easy to
talk to. Especially Takahiro. He always checks our
experiments and gives us advice when things don’t turn out
well, which encourages us when we feel like giving up!
Takahiro
Our team’s job is to create new technology, so developing
this equipment is no simple task. When things continue to
go wrong, you can’t help but feel discouraged. But I try
to interact with my teammates in a way that keeps them
positive because I want them to enjoy their work.
Hiroki
Takahiro is really easy to talk to. There are times when
just explaining what is troubling me to Takahiro helps me
clarify the problem, and the advice he gives me is
sometimes the key to solving it. I’m very grateful.
Usually, I don’t think you get very many opportunities to
speak with your department head. But on this team, our
supervisors will often drop by and ask how everything is
going. It puts me at ease knowing that they are taking a
keen interest in my efforts, and I also find it
motivating.
Takahiro
On this team, we always have to be quick to integrate the
world's cutting-edge technologies into the solutions we
are developing. Moreover, what is cutting-edge today, will
become commonplace five or ten years down the line. That’s
why we have to look five years into the future and be
creative in coming up with new equipment. But that is what
makes this job hard—things don’t always go as planned
because there are no precedents for what we are trying to
develop, and you have to rely on your team's expertise and
intuition to build something new. Nevertheless, I think
that this experience will certainly pay off when our young
members like Hiroki and Xiaoying are shaping the future of
our plants five or 10 years from now. I encourage them to
take an interest in new ideas and continue challenging
themselves.
